Abstract: A flowmeter failure determination method includes: a step of measuring a filling amount of hydrogen gas filled in a fuel tank of an automobile, using a flowmeter; a step of acquiring information of a pressure and a temperature of the fuel tank; a step of calculating the filling amount of the hydrogen gas filled in the fuel tank based on the acquired pressure and temperature and a capacity of the fuel tank in which an expansion rate of the fuel tank is considered; and a step of determining presence or absence of a failure of the flowmeter using an error value between the measured filling amount and the calculated filling amount.

Abstract: A gas filling device is provided with a first gas supply pipeline, a second gas supply pipeline, and an integrated control panel. The first gas supply pipeline supplies hydrogen gas from a multistage accumulator to a first filled tank mounted on a first vehicle. The second gas supply pipeline supplies hydrogen gas from the multistage accumulator to a second filled tank mounted on a second vehicle different from the first vehicle. At the time of filling the hydrogen gas into both of the first filled tank and the second filled tank from the multistage accumulator, the integrated control panel sets a pressure rise rate of the first filled tank or a pressure rise rate of the second filled tank to be lower than a reference pressure rise rate in accordance with a difference in pressure between the first filled tank and the second filled tank.
